1. Symmetric varactor frequency multipliers
Sammanfattning : This thesis describes heterostructure barrier varactor (HBV) frequency multipliers for millimetre and sub-millimetre wave applications.The basic principles of HBVs are explained. Starting from basic varactor theory, an equivalent circuit model for HBVs is presented. LÄS MER
2. Modelling and design of high-power HBV multipliers
Sammanfattning : This thesis deals with symmetric varactor frequency multipliers for millimetre and sub-millimetre wave applications. Much of the material presented is general and applicable to any type of (symmetric) varactor, but the focus is on the heterostructure barrier varactor (HBV). The basic function and principles of HBVs are explained. LÄS MER
